Complete the Georgia Virtual course and read through Teach Astronomy. Go through the lessons at the Astronomy Class Online site. Watch the Khan Academy videos. (Choose which videos. Some are more applicable to Earth Science studies.)

Visit the Astronomy Today website and work through the multiple choice, labeling, practice problems and true/false questions. Note: The animations clips may not work on current versions of Windows Media Player, but can be played on Real Player (free download). Copy the animation clip URL by right-clicking on the link and selecting "Copy Shortcut". In Real Player, click --> File --> Open, and paste in the link.

Use the additional resources to study more about specific topics, such as "the Solar System." Finish with the practice test, then one of the final exams.

Visit your local library for more information on astronomy, if needed.
